It’s 1:02 am and I don’t even have a mustang....but I do want to install a cam on my non existent Mustang after watching this

[@jhershy1381]

You should do that. Dreams are real

[@blackpanther04ltc91]

I had that dream for a while then it finally came true you should keep dreaming don't give up

[@checo_1777]

It’s been 3 years, did you ever get a mustang?

Aaaaawwww yuss. I haven't been this excited for an upgrade video since the ITBs for the S2000!

Enjoying the Mullet Mustang series. Would love to see the same kind of videos, you buy a car and work on it to make it better for track, not just drag. Would love to see you compare the same era cars like 2005 G35 which was a competitor to this.

[@Adam_824]

Always enjoy your guys content

[@JDIZZY024]

I have a 05 f150 with the same engine I'm looking to do a cam swap, with this greatly detailed video I feel that I could do it myself 👍🏻

[@Tomatokillz]

man i had to come back and watch this again, I miss this intro! should bring it back for the nostalgia one time

[@milieu675]

Replace lash adjusters and rockers as well at this point 👌

[@Large_Sarge]

Ive seen curved jaw vice grips used also. It's cringe but has to be done sometimes. Just got some ford performance cams and long tube headers for my 09 S197. Can't wait to do this job. Thanks for this video.

[@Girz0r]

Nice work guys!

[@marxieuwu3573]

I would absolutely love to see you guys work on a 2000 Lincoln Town Car, make a super cool sleeper build, since it's a Ford Modular V8 it shares many performance parts with the older Mustang V8. Cams,headers,turbo or blower and big meaty tires

[@BoostedMarcelo]

Good job guys!! Changed my springs, cams and timing chains on my 2007 GT and it was a badass experience

[@speedacademy]

We certainly dont want to do this again... ever haha

did this on mine but used ford hotrod cams, easy to work on love my 3v 4.6

[@kkacperowski]

You guys are SO NICE!

[@feellnfroggy]

If you set the crank at about 12-14 deg from top dead center, you hit a spot in the cam where no valves are under spring pressure (or are all under equal pressure, and when you release the cam pulleys, they wont spin on you, and you don't lose alignment with the crank. Little tips from hard lessons learned.

[@rondaroushy651]

God Bless you, I'm going to be doing an entire top end rebuild with new timing components and I was wondering if there was a spot where no springs are under pressure.

[@BJ-fk9sq]

So is it 12-14 degrees before you hit tdc? Or 12-14 degrees after you hit tdc?

[@feellnfroggy]

@@BJ-fk9sq when you rotate the crank with valve covers removed, you will see when you hit that sweet spot. No pressure on any of the valves.

[@BJ-fk9sq]

@@feellnfroggy ok, thank you!

When will you guys have an update on this build! Exactly the mods I want to do with my 3v. Looking forward to more great content.

[@damianfro4855]

The mustang I bought was a half finished project, I put 5.4 cams from a 3 valve truck, and I havent had problems so far. If u want a more mean sound, do it. I didnt have a choice, cause I was on a budget, and I could not find any 4.6 3 valves in the junkyard

[@ZakPhol]

Great video! At 18:21, I can so relate. :-)

[@MasterChief-sl9ro]

All you have to do is remove the intake rocker that has pressure on it. The cam will not move when removing the phaser...

[@juliozarate7681]

I love the his Chanel great stuff

[@barsaf9989]

Great vid. A lot of smaller channels finally popping up with great content

[@garymcmullin2292]

the more I watch work done on the top of those modular motors the more I like the old pushrod motors. For grip on the cam body when lining up the phaser sprocket try a small piece of leather or Naugahyde in the jaws of the pliers.

[@twportre8809]

Damn there's that Tim Horton again lol ... I must come to canada to try out this mans stuff. I thought it was just coffee because my good friend Jeff Thorman Brings his Tim Hortons. Now you said FOOD so I MUST MUST try him out now.

I use pearl necklace drop it down the spark plug hole till I got almost a whole necklace in there.. . and then I slowly roll the piston upward till it pushes on my pearls and my pearls hold my valves in while I make spring seal changes... and it works on all engines..use it on lawn mowers to.....

Sorry, NV was closing so we had to hurry and we thought the dyno video would be ideal to show the exhaust note off

No worries fellas, keep pumping out the good content on that stang.

[@johnnychambers1015]

hello i was wanting to know where did you get your blue hound valve spring compression tool im need one.

[@jacchatain554]

Any break in procedure for post install? I've seen comp cam that needed a 15min run in at 2500rpm to properly set and harden the wear surfaces on the cam lobes.

[@doctorlobsteroctopus]

So you guys work full time for NV now, right? ;) I bet it's really a nice benefit to be able to work in the heated shop, and have a lift too! Great video as always, guys.

[@speedacademy]

Is it ever! We'll be back in the chicken coop soon though, spring and warm weather are almost here.

[@ryanv7195]

Wow great video! I'm gonna subscribe. So why do you think they want you to remove the roller followers before the cam if you cam do it your way and just take them off after the cam is up and out?

does the special tool also stop the tensioner from drawing up the chain bc im surprised it didnt get way too tight

[@austinlarkin5242]

I know this is a few years old at this point, but how much psi of air would you guys recommend using in the spark plug socket to keep the valves up? Thank you!

[@lordXguru]

stage 3 or 4 gives you that big lope you were mentioning

[@johnbarker5009]

That isn't nearly as bad as I expected.

[@seankelley4372]

What tool did you use to screw into the spark plug hole to hold the valves closed?

[@truthteller9562]

What a let down no bumpty bump

[@UnderAchievrLP]

I know the car Pete's Evo is pretty much complete but i hope some stuff is possible for some content lapping or just random updates. There is only so many times I can watch the videos of it!

[@speedacademydave]

We're definitely going to do a track test of it this summer, since we're swapping out the coilovers for some Fortune Auto 500-series. Pete wanted something more comfortable for the street that's still track-capable, so we'll see how he likes the 500's.

[@UnderAchievrLP]

Awesome really looking forward to it!

[@jonathanwaugh1433]

waiting for the dyno run

[@Gear1993Head]

Is the compressed air into the engine to keep the valve from dropping into the cylinder?

[@BrookieCooki84]

Gear1993Head xxx correct

[@JonahNAloha]

Does the camshaft have to be flushed with the heads when torquing the caps down?

[@greyhatchgamecock]

where did you buy the spark plug air hose i cant find one? the ones i am finding are 14 and 18mm i was told the 3v is 16mm help me out if you can thanks

[@dennyramsey8774]

I usually just take my phone and take lots of pictures if im doing a job where i have to remember where and how alot of parts go,, i still use a box very similar to theres...

[@rosskothe382]

How much pressure are you putting into the cylinder? Looking to do this

[@jaredstafford5565]

I have a question my son's 05 was making some valve spring noise and his car died and won't even turn over is there some kind of sensor stopping it from turning over or did it drop a valve and seize maybe?

[@coyoteb3ast772]

will that intake manifold fit my 00 ford expedition 4.6l 2v ?

[@ryanv7195]

What did you do to prime the engine?

[@sdonaghey]

Where do you guys go for your dyno? Is it somewhere in Hamilton?

[@therealboofighter]

Was there a break in period that you had to do that you did not show us? I only ask because there was one for the cams I put in my MR2.

[@speedacademy]

No, hydralic lifters and lash adjusters mean no break in. Start up and go.

[@Ballsandweiner]

:12 just gets me! haha

[@RobertKohut]

Great job, a little "back yard" but you got it done. A better sound clip , warmed up, and from the rear would have been nice. Sounded a bit "lopey", but hard to tell with the brief moment you had it running.

[@speedacademy]

We're saving it for the dyno video, lots of good noises coming!

[@thelittleterrorist22]

Are you guys going to be at Gridlife again?

[@vVeazel]

Hey guys, how did you prime the engine to lubricate the lifters?

[@cheeko_914]

Piss in it

[@adamj764]

have you guys tried some of the phaser lockout kits that are available?

[@speedacademy]

Comp Cams says we dont need them so we didnt see a need to install them.

[@JonSauce98]

what air tool was used to hold the valves up

[@arcorob]

Question(s) for you - I gather you used the compressed air because you cant crank the engine (manually) to get the valves up , yes? Does the air hold them all up or did you move the air line? Second - have you seen the Lisle 36200 Valve Keeper Remover and Installer tool ? Wonder if it works on a mustang...watched on a Honda and it was awesome....put this in the youtube search box "replace valve stem seals - with cylinder head on" and tell me what you think...would save folks ALOT of time

[@speedacademy]

Correct, the compressed air is one of the best ways to ensure you dont drop a valve into the motor. It pressures the cylinder and holds the vales up. Never seen that tool in action on a Mustang, it could work but we've always trusted the compressed air method.

[@theroncrittenton4256]

Where did you get your valve spring too lol from?

[@James-wg5pe]

How Did you guys prim the engine??i can’t find out anywhere

[@HvacPanda]

Guessing these are the 127300s? No lockouts/limiters to the phasers to do the 127500s? :( hope it makes some power regardless

[@speedacademy]

Nope, they state no limiters needed.

[@guynoir3116]

The one downfall of a cams swap on a 3 valve is that the stock bottom end will probably fail , catastrophically , if used frequently at R.P.M.s approaching 6400 .

[@flubdreload2818]

Richard Skipper most likely the stock rods can’t handle 6,400RPM+. Connecting rods are under a lot of tensile and compressive loads constantly and if you’re approaching 6,500+ RPM consistently, you’ll probably end up snapping a rod. the crank is pretty stout so i doubt its the crank that’ll go first.
